Electric power is recreation habits and the fundamental patterns of communication and cohabitation in modern societies. The effects of an electrical shock can range from an unpleasant tingle to cardiac arrest and death. Electrocution occurs accidentally in the majority of cases as household or work accidents. An electrical shock is received when electrical current passes through the body. Electrocution is a not uncommon cause of death in forensic pathology. Deaths occur mostly at a voltage between 1lo-380 V which is the voltage range of home and industrial electricity. Nowadays electrical injury is increasingly becoming a significant health problem in world, especially in rural areas due to the increasing uptake of electricity for agricultural development purposes. Amperage is the most important factor in electrocution. Since voltage is usually constant, the main factor in determining the amount of amperage that enters the body is the resistance. Diagnosis of electrocution is not an easy issue and makes a great challenge for both physicians and forensic pathologists especially with lack of history of exposure to electric forces.The mechanisms of death in electrocution are described according to the current pathway and the amount of current. It is believed that most deaths from electrocution are due to ventricular fibrillation. Very-high-voltage electricity such as lightning may cause thermal injury simply by passing close to the body.
